DOOR STOP AND HOLDER.

Application filed July 12,

To all whom. it may, concern Be it known that I, lutnnron H. Fonon, acitizen of the United States, and resident of Danville, in the county ofVermilion and State of Illinois, have invented certain new and usefulImprovements in a Door Stop and Holder, of which thetollowing is aspecification.

My invention. relates to door holding devices and particularly to novelmechanism having unusual characteristics of etliciency and certainty ofoperation.

It is common to employ a door stop or holder particularly on doors whichutilize a spring closer. Such stops are so constructed that by a singlemovement of the foot the door holding device may be firmly positionedand released as desired. However, some difficulty is experienced insecuring efficient operationwhere the floor adjacent to the door isuneven, due to the fact that there is insufficient contact of the rigidholding device with the floor.

In the device of this invention I provide means whereby thefloor-contacting foot, which is usually of rubber or similar resilientmaterial has a limited capacity for universal movement, the connectionbeing in the nature of a ball and socket joint thus insuring that theflat contacting face of the foot shall have an even bearingnotwithstanding any irregularities in the floor with which it is adaptedto engage. Furthermore, the construction is such that it is impossibleto bind the ball and socket connection by reason 01"? an extremepressure applied to the plunger, the foot member being resiliently heldin proper position notwithstanding any actuation of the plunger.

The invention. will be more readily understood by reference to theaccompanying drawings, wherein,

Fig. 1 is a front elevation of a device constructed in accordance withmy invention;

Fig. 2 is a longitudinal sectional view through the device; and,

Fig. 3 is a plan view.

In the drawings it will be seen that I provide a housing or casing 10 ofgenerally tubular form having attaching lugs 11, 12, by means of whichthe device may be secured to a door at its lower edge. The casing isprovided with two transverse walls 13, 14:, which are apertured toaccommodate the plunger 1.5. An expansion spring 16, mounted in thespace between the two transverse walls,

surrounds the plunger and engages a pin 17,.

carried by the plunger. As a means for retaining the plunger in adesired position I provide a catch consisting of a plate 18, normallyheld in the position shown in the drawings by means of a short spring 19and provided with a lug or projection 20, adapted to be inserted withinan aperture 2i, ithin the back plate which forms a part of the casing.The operation of the plunger and the catch being well, known, will notbe described in. detail.

The holding member or foot which 1 prefor to employ has a circularrubber member 22 suitably held within a flanged disc 23, to which isriveted a ball member 211. The ball is held within a. socket provided inthe lower portion of a tubular member and engages a metailic disc 26,also carried within the tubular member. which disc rests upon an annularshoulder 27, so positioned that the space provided for the ball is justsuflicient to insure contact between the ball and the disc. A coilspring 28 extends between the disc and the lower end of the plunger 15,the downward force exerted by the plunger being transmitted to the footmember through. this spring.

The lower end of the plunger is guided within the tubular member 25 bymeans of. the collar 29 and is held in proper relation to the tubularmember by means of the transverse pin 30 which engages a slot 31 in theplunger and a slot 32 in the tubular member 25. A rubber washer 33surrounds the plunger and is positioned between the upper end of thetubular member and the trans verse wall 13.

In operation it will be seen that a downward force applied to theplunger exerted against the spring- 28 thus causing the downward traveloi the tubular member and its connected parts to a point at which therubber foot engages the floor. Any continued downward pressure appliedto the plunger results in compressing the spring 28, as permitted by thepin and slot connections 30, 82. At this point it will be seen that thefoot member is resiliently held against the floor and that if there areany irregularities in the floor the foot member may accommo date itselfthereto by reason of: the ball and socket connection through theplunger. This insures, furthermore, a more secure holding action thanwould otherwise be pos sible. U 3011 arelease of the lun er it willretract to a slight extent until gripped by the catch 18 and this slightreturn move ment will. be permitted due to the slot 31 and withoutchange in the position of the tubular member 25. WVhen the plunger andits associated parts are to be released a down- V ward force is appliedto the catch 18 whereupon the spring 16 will cause the return of theplunger, the shock thereof being absorbed by the rubber washer 33.

Obviously the construction is capable of considerable modification andsuch modifications as are within the scope of the claims I considerwithin the spirit of my invention.

I claim: 7

1. In a door stop the combination of a casing, a plunger therein, aspring acting to resist downward movement of the plunger, a catch forthe plunger, a tubular member in the lower end of the casing andseparate from said plunger said member providing a socket, a foot havinga ball to engage said socket, a spring between the lower end of theplunger and said foot, and a pin and slot connection between the plungerand the tubular member.

2. In a door stop the combination of a casing, a plunger therein, aspring acting to resist downward movement of the plunger, a catch forthe plunger, a tubular member in the lower end of the casing andseparate from said plunger said member providing a socket, a foot havinga ball to engage said foot, said plunger and tubular member beingslotted, and a pin connecting said members through said slots.
